Sep 14, 2012 at 23:16 comment added Christian The question is about i2c! My experience is with a DS18B20 with a bit banging process in the kernel (Occidentalis release). Yes, I made my python program not to accept the new value if the CRC check wherent ok. So that loop could take some extra time.
Sep 14, 2012 at 8:12 comment added Krzysztof Adamski You could post your python code so we can see what exactly it is doing. It probably waits for sensor to be ready since it takes some time for DS18B20 before you can read temperature value.
Sep 13, 2012 at 21:48 comment added John La Rooy DS18B20 is a 1-wire interface, not i2c
